Her oesophagus was too small, which meant she had to undergo a series of operations to help her eat.

She has previously called the imperfection her "least favourite body part," but now by showing it off, it has inspired girls around the world to do the same.

"It's so inspiring that you own your insecurities and love yourself," one fan wrote.

"An inspiration for all of us who have them! Thank you Perrie," said another.

"Thank you, Perrie, for helping me and many other people feel more comfortable and confident about showing our scars. I had a pacemaker fitted 18 months ago, and don't show my scar (and the lump that has come with it) often. But you know what? Why should we hide them? They make us who we are," another passionate fan wrote.

Some have even gone as far has tagging Perrie and her pic alongside their own #scars, and it's making waves online.
